Comparative susceptibility of mosquito populations in North Queensland, Australia to oral infection with dengue virus.

Dengue is the most prevalent arthropod-borne virus, with at least 40% of the world's population at risk of infection each year. In Australia, dengue is not endemic, but viremic travelers trigger outbreaks involving hundreds of cases. We compared the susceptibility of Aedes aegypti mosquitoes from two geographically isolated populations to two strains of dengue virus serotype 2. We found, interestingly, that mosquitoes from a city with no history of dengue were more susceptible to virus than mosquitoes from an outbreak-prone region, particularly with respect to one dengue strain. These findings suggest recent evolution of population-based differences in vector competence or different historical origins. Future genomic comparisons of these populations could reveal the genetic basis of vector competence and the relative role of selection and stochastic processes in shaping their differences. Lastly, we show the novel finding of a correlation between midgut dengue titer and titer in tissues colonized after dissemination

Photography-based taxonomy is inadequate, unnecessary, and potentially harmful for biological sciences

The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed by the Code has already been discussed in Zootaxa (Dubois & Nemésio 2007; Donegan 2008, 2009; Nemésio 2009a–b; Dubois 2009; Gentile & Snell 2009; Minelli 2009; Cianferoni & Bartolozzi 2016; Amorim et al. 2016). This question was again raised in a letter supported by 35 signatories published in the journal Nature (Pape et al. 2016) on 15 September 2016. On 25 September 2016, the following rebuttal (strictly limited to 300 words as per the editorial rules of Nature) was submitted to Nature, which on 18 October 2016 refused to publish it. As we think this problem is a very important one for zoological taxonomy, this text is published here exactly as submitted to Nature, followed by the list of the 493 taxonomists and collection-based researchers who signed it in the short time span from 20 September to 6 October 2016

Minimal information for studies of extracellular vesicles (MISEV2023): From basic to advanced approaches

Extracellular vesicles (EVs), through their complex cargo, can reflect the state of their cell of origin and change the functions and phenotypes of other cells. These features indicate strong biomarker and therapeutic potential and have generated broad interest, as evidenced by the steady year-on-year increase in the numbers of scientific publications about EVs. Important advances have been made in EV metrology and in understanding and applying EV biology. However, hurdles remain to realising the potential of EVs in domains ranging from basic biology to clinical applications due to challenges in EV nomenclature, separation from non-vesicular extracellular particles, characterisation and functional studies. To address the challenges and opportunities in this rapidly evolving field, the International Society for Extracellular Vesicles (ISEV) updates its 'Minimal Information for Studies of Extracellular Vesicles', which was first published in 2014 and then in 2018 as MISEV2014 and MISEV2018, respectively. The goal of the current document, MISEV2023, is to provide researchers with an updated snapshot of available approaches and their advantages and limitations for production, separation and characterisation of EVs from multiple sources, including cell culture, body fluids and solid tissues. In addition to presenting the latest state of the art in basic principles of EV research, this document also covers advanced techniques and approaches that are currently expanding the boundaries of the field. MISEV2023 also includes new sections on EV release and uptake and a brief discussion of in vivo approaches to study EVs. Compiling feedback from ISEV expert task forces and more than 1000 researchers, this document conveys the current state of EV research to facilitate robust scientific discoveries and move the field forward even more rapidly

A análise da vigilância de Foucault e sua aplicação na sociedade contemporânea: estudo de aspectos da vigilância e sua relação com as novas tecnologias de comunicação

The present article discusses the analisys of surveillance proposed by Michel Foucault. Some features of modern surveillance exposed by the philosopher are analyzed and subsequently, thought regarding the configuration of contemporary society. It is a theoretical-analytical reflection on the relations between surveillance in modern society and contemporary society, which is defined by the insertion of new communication technologies, highlighting the internet.O presente artigo aborda a análise da vigilância proposta por Michel Foucault. São estudadas algumas caraterísticas da vigilância moderna, as quais o filósofo expõe na sua análise, e, na sequência, estas são pensadas em função da configuração da sociedade contemporânea. Trata-se de uma reflexão teóricoanalítica a respeito das relações entre a vigilância nas sociedades moderna e contemporânea; esta última, definida pela inserção das novas tecnologias de comunicação, entre as quais se destaca a internet

The Domestication of Annatto (Bixa orellana) from Bixa urucurana in Amazonia

Annatto (Bixa orellana) is an important colorant domesticated in theNeotropics, although it is not clear where or from which wild populations. We reviewed the available biological, archaeological, and ethnographic information about annatto, and integrated this with our recent ethnobotanical observations of cultivated and non-cultivated populations in order to evaluate the hypothesis thatwhat is classified as Bixa urucurana is the wild ancestor of cultivated annatto, Bixa orellana. Most B. urucurana populations we found in Amazonia occurred in open forests or anthropogenic landscapes, although never cultivated, and always associated with riparian environments. While cultivated annatto always produces abundant pigment, B. urucurana populations that we observed contained variable amounts of pigment, fromvery little to nearly the amount of cultivated annatto, suggesting gene flow fromcultivated to non-cultivated. Bixa urucurana has indehiscent fruits, which indicate changes in dehiscence during annatto domestication, a notable feature rarely found in other tree species. Local residents identified the non-cultivated populations aswild annatto (urucum bravo), and they emphasized their smaller fruits with less pigment, their spontaneous regeneration, their non-use, and that they hybridize with cultivated annatto. Ethnography identified the symbolic importance of annatto, but an explicit mention of origin only comes from southern Amazonia. Although the oldest annatto archaeological record came from the Caribbean, domestication occurred in northern South America, since B. urucurana does not occur in the Caribbean. Traditional ecological knowledge and morphology identified the close relationship between B. urucurana (never cultivated) and B. orellana (always cultivated). Evidence reported here strongly supports Kuntze's (1925) suggestion that Bixa urucurana Willd. is a variety of B. orellana L., thus identifying the wild ancestor of cultivated annatto. © 2015, by The New York Botanical Garden Press, Bronx, NY 10458-5126 U.S.A
